SPRING WHEEL.

10 all fio/wm t 'may concern.'

Be it known that I, FRED BENTLEY, a citizen of the United States, residing at Detroit, in the countyl of-Wayne and State of Michigan, have invented new and useful Improvements in Spring 'Wheels, of which the following is a specification.

This invention relates to improvements in spring wheels and has for an object the provision of a wheel of this character which includes inner and outer concentrically arranged relatively movable rim members of tubular formation, to provide for strength and lightness of construction, together with means for yieldingly holding` the members separated and means for preventing rela' tive lateral movement of said members.

The invention further includes removable means for closing the space between said members to exclude dust, dirt and moisture and thus prevent undue wear of the parts and to insure proper functioning of the latter.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a side elevation of a spring wheel embodying the invention.

Figure 2 is an enlarged lsection taken transversely through the rim.

Figure 3 is a section on the line 3 3 or Figure 2.

IFigure l is a fragmentary plan view lookinor at the inner face of the rim.

igure 5 is a section on the line 5-5 of F i re 3.

lferring in detail to the drawings, wherein like characters of referencel denote corresponding parts, the improved wheel which may be either of the disk, artillery, wire spoke or other suitable well known type, includes an inner rim section 10 and an outer rim section 11. These sections are of tubular formation to insure strength and lightness and are arranged one within the other in spaced relation.

Each of these rim sections is provided with spaced opposed pockets 12, herein shown as of rectangular shape. Any number of these pockets may be provided as desired, the number being governed by the yuse for which the wheel is intended. Lo-

cated within each of thenpockets is "a coiled spring S13-whose `function -is ,tov yieldinglyl holdthe rim Vvsections separated so as:y to" provide the desired f resiliency infthe'Vl 'fwheel- The pockets of the inner rim section arer1 bolts or screws 15, so that access may be had to the pockets for the purpose of removing or replacing the springs, or for the insertion of proper lubrication.r Positioned within each of the pockets and surrounding the springs is a tubular housing 16, whose sides have -a sliding engagement with the adjacent walls of the pockets to provide free radial movement of the rim sections, but prevent relative lateral movement and form guides for the rim sections. The tubular housings 16 are connected to 'their respective springs by means of clips 17 formed bv striking up lugs from opposite sidesof the housing.

The rim sections 10 and 11 are provided in their outer faces with seats 18 and positioned-within these seats are compressible ring members 19, which may be formed of rubber or like material. The rings 19 are held in place by removable rings 2O secured by screws 21. This permits of the removal of the rings 19 and their replacement when necessary. The rings 19 act to exclude dust,

dirt or other extraneous matter so as to pro-y tect the interior of the rim andy at the same time permit of proper relative movement of the sections.

If desired, the rimmay be provided with a tread 21 of suitable construction. The tread is preferably formed of rubber or other compressible material and is held in place by means of annular anges 22 provided on the rim section 11.

The wheel illustra-ted'in the drawings vis of the ywire spoke type and the spokes 23 are shown as secured to the inner rim section 10 in staggered formation.

The invention is susceptible of various changes in its form, proportions and vminor details of construction and the` right is herein reserved to make such changes as properly fall within the scope of the appended claims` y Having described the invention whatv is claimed is 1. A spring wheel comprising inner and outer concentrically arranged annular tubular members, spaced opposed pockets located therein, a spring positioned in each pair of said pockets for yieldingly holding the members in spaced relation, and a tubular casing;` secured to and surrounding each of the springs for sliding engagement with the Walls of the pockets and defining guides.

2. A spring Wheel comprising inner andl outer concentrically arranged annular tubular members, spaced opposed pockets provided therein, ja spring positioned in each pair of said pockets for yieldingly holding` the members in spaced relation, a tubularcasing secured to and surrounding each 0i i sans? Walls of the tubular members, compressible rings positioned in said seats and spanning the space between the members and retaining rings removably secured Within said seats for removably securing the coinpressible rings in position.

n testimony whereof l affix my signature.

FRED BENTLEY.
